Is design for cement bond logging and investigation of open-hole sections by kinematic and dynamic parameters of elastic waves. 

Description

Problems to be solved

• identification of low-strength cement intervals, detection of volume-contact defects of cement bond;
• lithologic segregation of a section, identification of reservoirs and evaluation of reservoir porosity.

Features and Advantages

• ZAS-02 and ZAS-03 tools with a three-element probe construction and an electronic circuit are fully compatible with the equipment – UZBA-21 and UZBA-21, widely used in Russia;
• replacement of the out of date downhole tools in UZBA-21 and UZBA-21A equipment by ZAS-02 and ZAS-03 tools keeps up using of the running investigation methods, the respective techniques as well as the interpretation software;
• tool conveyance to the investigation interval through the drill pipe with inner diameter 90 mm.
